Ok, couldn't wait to post the new deb since I got the scalable icons fixed.
Also added descriptions for folders. Now it is showing the number of folders and files in that directory.

For the applications descriptions I still haven't found a way so I am printing the comment field for those apps which have a proper comment.
If someone knows how to get the proper descriptions please let me know.

The bookmark in a folder issue is also fixed.

Please test and post bug reports.
